S30v and s35vn are excellent. I have two fixed blades in these steels. They perform extremely well in the outdoors. I use my knives to carve, baton, feather stick not cut cardboard mind you...
I used to have trouble sharpening S30v when first introduced to CPM steels. It would have been easy to blame the steel but I would have missed out. After learning how to sharpen, I have come to really appreciate S30V. It doesnt take too long to sharpen, it holds its edge long enough, it is stain resistant and its price is reasonable. Especially from Buck and Spyderco.
I've used and sharpened S30V pretty extensively (actually more than even M390 which I am far more fond of), and it does seem to be a very difficult to work steel, granted not like S110V which basically laughed at my DMT XC stone. A reprofile on M390 or Elmax will take me like 2 hours if it is very extreme, but I've had S30V take nearly 2 hours with a belt sander (of course dipping the blade and taking quick breaks to ensure no steel overheating). Taking an S30V blade down about 8° per side took me 6 hours one day because I had to work with with my DMT XC stone. Even taking Elmax back 10°+ didn't take nearly as long (one of those ZT factory edges...). S35VN isn't nearly as bad as S30V, though.I’m genuinely not sure why some find it difficult or annoying to sharpen “S series” steels. What are you people using, a bar of soap? Or do you let your knives get completely blunted and then reprofile the edge completely?

2 hours to reprofile s30v with a BELT SANDER? I don't know if you realize this but you're on a knife forum where tens of thousands of other knife users congregate. Spewing baloney like it takes 2 hours to reprofile s30v wirh a belt sander is a sure way to be called out for exaggerating A LOT or just blatant lying.I've used and sharpened S30V pretty extensively (actually more than even M390 which I am far more fond of), and it does seem to be a very difficult to work steel, granted not like S110V which basically laughed at my DMT XC stone.

I am not trying to pull a Gaston. I was using light pressure, as is recommended with a sander, and I had a lower grit belt (I think it was a 320 or so). The belt was definitely old, and likely needed to be tossed, but it was what I had with me.
It depends on what you are using the knives to cut. In the kitchen, I see a huge difference between VG10 and 440C, with VG10 blades holding an edge 3X longer. My kitchen knives go some time between sharpening, so it is hard to see a large advantage for S35V over the VG10. It is there, but small. My Tojiro kithen knives in VG10 are RC60 or so, while my S35V are either RC60 or 58-60 Warthers. When fishing, I needed to sharpen my VG10 Fallkniven fishing knife after every use, and cutting the heads off fish dulled them quickly. My knives in S35V had far less edge damage. It is possible that the Fallknivens needed some sharpening work before use, but I will find out next trip to the beach.Easy to sharpen, but it dulls to a "working edge" very fast. For me VG-10 performs better. Doesn't stay sharp as long, but the difference is marginal for the performance.
No offense taken. I do disagree with the belt sander destroying a knife, though. Aside from that one clear outlier, it gave me spectacular edges in very little time, many times I could reprofile 2 or 3 knives in a little over 30 minutes, and by knowing the limitations and risks (and how to mitigate said risks) I was able to get pretty uniform edges in very little time. That said, I do prefer a stone, especially on a guided system, to the sander, because while it is slower there is comparatively little risk of a muscle jerk butchering the knife.A dull belt doesn’t cut, it generates heat.
320 grit isn’t a ‘lower grit.’
Your little grinder, even with ‘light pressure’, is a surefire way to destroy the edge of a knife.
As a rule, I try to stay out of threads like this, especially when they involve catastrophes like Gaston444, who as far as I can tell knows absolutely nothing about knives, and is hellbent on proving it every time he opens his mouth, but there’s already far too much misinformation on the internet involving BAD anecdotal evidence, which I’m afraid to say is what you’re giving.
I’m sorry if this singles you out - it’s genuinely not my intention to alienate you or humiliate you, but I’m concerned that there might be folks out there that may believe that the correct course of action for sharpening is on a crummy Chinese belt grinder moving a Mach 5 with a wornout 320 grit belt, after reading it from someone they perceive as having more information than they do.
I figured you’re looking to sharpen high wear resistance steels, especially those with considerable amount of vanadium carbide, use diamond stones. They’re the right tool for the job, won’t generate heat the way a belt grinder will, and will quickly sharpen even the most wear resistant of steels.

Sharpening time can vary a lot. It depends on the user's skill level and the tools being used. What takes one man 2 hours on a grinder can take another man a fraction of that. As i have become more proficient at sharpening, my amount of time spent has dramatically reduced. Betters techniques and best practices, fewer errors.
And that, my friend, is the point in a nutshell.That said, i normally will have my s30v touched up on ceramics in a few minutes.
...BTW, I bought one of those HF sanders for my SO so she could do broken glass mosaic work. I would believe it if he said it took two day on that POS to get what you wanted from it. It is too light weight, doesn't track well, and doesn't have a good place to put the knife to sharpen or reprofile. Overall, if you didn't really need a sander or were just an occasional user they may be fine. But for real use, it would be pretty challenging to get anything use out of it. The one I have hasn't been turned on in about 10 - 12 years...
